QUALITY AND RELIABILITY:

A COATES COMMITMENT SINCE 1955

Since we built our first pool heater in 1955, Coates has been the name to trust for quality and reliability in water heating equipment.

Today, the Coates Heater Company manufactures the largest, most complete selection of electric heaters for pools and spas. All Coates models, from our largest capacity

300kw commercial pool heater to the smallest 1.5kw in-line spa heater, blend the latest technology, the finest materials and innovative engineering to provide the kind of quality and reliability you've come to expect from Coates. Easy to use sizing calculator available at our website.

There are two ways to size a pool/spa. Either by the heat loss, which is used for maintaining the temperature, or the temperature rise, which is used when heat up time is a factor.

TEMPERATURE RISE METHOD:

For use when a rapid change in temperature is important.

(common for spas)

HEAT LOSS METHOD:

For use when maintaining water temperature.

(common for pools)

V = Volume of pool/spa in gallons

= Length x Width x Depth x 7.5

kw = Kilowatt rating of heater

D T = Temperature rise in °F/hour

Do you want to know the kilowatt required to achieve a desired temperature rise?

kw = V x 8.3 x DT*

3413

Do you want to know the temperature rise a kilowatt rating will achieve?

D T = KW x 411*

V

A = Surface area of pool/spa (ft 2 )

= Length x Width

T = Difference between average air temp and desired

water temp (°F).

kw = Kilowatt rating of heater kw = A x T x 10**

3413

** Assumes a heat loss of 10 BTU/hour per ft 2 per °F.

Assumes a 3-1/2 mph maximum wind and

partial sun exposure. 1kw= 3,413 BTU/hour

* Assumes spa is covered when not in use.

Formula does not account for heat loss — actual heat

up times may vary.

The built-in pressure switch prevents operation when there is no water flow and allows operation at flow rates between

15GPM and 80GPM. The stainless steel tank is designed to optimize heat transfer by directing the water flow over the incoloy elements efficiently.

STANDARD FEATURES:

> Incoloy heating elements

> Close differential thermostat

> Manual reset high temp limit

> Pressure switch

> Heavy duty contactors

> Element & flow "on" lights

> Piping connections:

1-1/2 x 2" union connections for PVC pipe
